    "server":"x.x.x.x",  # Shadowsocks server address
    "server_port":1035,  # Shadowsocks server port
    "local_address": "127.0.0.1", # Local IP
    "local_port":1080,  # Local port
    "password":"password", # Shadowsocks connection password
    "timeout":300,  # Wait timeout
    "method":"aes-256-cfb",  # Encryption method
    "fast_open": false,  # true or false. Turn on fast open to reduce latency, but require the Linux kernel to be in 3.7+
    "workers": 1  #Number of worker threads 
}
